What is giant cell arteritis (GCA)?

Giant cell arteritis (GCA) is an inflammatory disease that affects the lining of the arteries. This inflammation can cause a narrowing or blockage of the blood vessels, which interrupts blood flow. GCA is common in the arteries in your head and in your temples, which is why it’s sometimes called temporal arteritis.


Spotting GCA Symptoms


Signs of GCA often appear as headaches, scalp tenderness, jaw pain, and problems with seeing clearly. Corticosteroid medications usually relieve symptoms either right away or within a few days of treatment, and may prevent vision loss. However, even with treatment, relapses are common. If left untreated, GCA may eventually lead to blindness.
